Chapter 6: Static Port Trunks
120 Section I: Basic Operations
Modifying a Static Port Trunk
This section contains the procedure for modifying a static port trunk on the
switch.
Caution
If you will be adding or removing ports from the trunk, you should
disconnect all data cables from the ports of the trunk on the switch
before performing the procedure. Adding or removing ports from a
static port trunk without first disconnecting the cables may result in
loops in your network topology, which can result in broadcast storms
and poor network performance.
Note the following before performing this procedure:
ˆ
If you are adding a port and the port will be the lowest numbered port
in the trunk, its parameter settings will overwrite the settings of the
existing ports in the trunk. Therefore, you should check to see if its
settings are appropriate prior to adding it.
ˆ
If you are adding a port and the port will not be the lowest numbered
port in the trunk, its settings will be changed to match the settings of
the existing ports in the trunk.
ˆ
If you are adding a port to a static trunk, you should check to be sure
that the new port is an untagged member of the same VLAN as the
other trunk ports. A trunk cannot contain ports that are untagged
members of different VLANs.
